The End Of The Game. (Red Dead Redemption 2)

Spoilered answer anybody please, who passed the game completely, along with Chapter 6, after all the story of when we play as John Marston, will we have open world and whether all these strangers and other passers-by, the tasks which need not take place at all, and whether the money/character/horse and so on after 4 or 5 chapters, when we will pass control over to John, I just wanted to go through the game slowly, 100%, but before the end of 4 chapters left quite a bit, and the end of the game I already know, so I want to finish the main story and immersed in the lore of the world of RDR 2, and in this regard, I have concerns that when we start to play for John all gone. Thank you.
